Finnish to English Bus/Financial Finance (general)

The excerpt below is from a description of how risk scores are assigned to currency traders:

"
Compliance-tiimi arvioi asiakkaiden profiilien perusteella, määrittääkö valittu raja-arvo heidät sopivaan riskiryhmään. Arvion perusteella voidaan kokeellisia raja-arvoja joko nostaa tai laskea.

Kohtia iteroidaan, kunnes compliance-tiimin arvion perusteella on saatu haarukoitua sopivat raja-arvot.
"

How would you translate "haarukoida" in this context?

The term is not hard to translate in isolation, but I can't quite grasp how it describes the process explained here.

Thanks

(PS -- If needed, I'd be glad to post more of the surrounding context.)
